My point guard is 5'9 and when he was 19 I single trained him in OD with a level 4 trainer for 6 weeks and he got 4 pops and then single trained him in passing for four weeks and he got 3 pops, plus during the season he also got an extra handling and ID pop. So if you spend 10 weeks training OD, which I would do with a guard with inept OD, you should theoretically be able to get him to Prominent OD.
I wish there were pigmen. You get a few of these pigmen walking around I'm looking a whole lot better. Then if somebody wants to fix me up at least they could say, Hey he's no pig-man!
